    环氧地坪漆施工缺陷“跑油“的原因

    2018-10-17 17:50:15 无锡盛发地坪科技有限公司 阅读

    环氧地坪漆施工中环氧地坪漆在被涂物表面收缩,形成似圆珠、针孔等形状大小不一,如水洒在蜡纸上一样,斑斑点点的露出底层,是经常碰到的问题,我们称这样现象为“跑油”。【造成环氧地坪漆跑油的原因】

    In the construction of epoxy floor paint, the surface of the coating shrinks, forming beads, pinholes and other shapes and sizes, such as water sprinkled on wax paper, spots exposed to the bottom layer, is a common problem, we call this phenomenon "run oil". [cause of oil running on epoxy floor paint]

    原因一:底层或涂料中混有油污、蜡质、潮气,影响了漆膜的附着力,漆膜的表面张力使漆膜收缩跑油。

    Reason 1: Oil, wax and moisture mixed in the bottom layer or paint affect the adhesion of the paint film. The surface tension of the paint film causes the film to shrink and run off oil.

    原因二:底层涂料内有不干性稀释剂,如煤油、柴油、干燥后未及时挥发就涂面漆。

    Reason 2: There are non-drying thinners in the underlying coatings, such as kerosene, diesel oil, and topcoat without timely evaporation after drying.

    原因三:底层漆太光滑,与面层的附着力小于面层涂料的表面张力而产生跑油。

    Reason 3: The primer is too smooth, and the adhesion with the surface is less than the surface tension of the surface coating and oil run.

    原因四:涂料的润湿性差或掺入过多的有机硅油,都不易形成一层均匀的膜层,容易发生跑油。

    Cause 4: The poor wettability of the coating or the addition of too much silicone oil, are not easy to form a uniform film, easy to run oil.

    【解决环氧地坪漆跑油的方法】

    [method for solving oil running off of epoxy floor paint]

    1、中涂层仔细打磨。

    1. The middle coating is carefully polished.

    2、薄涂溶剂质量控制好环氧地坪环氧地坪漆跑油的解决办法有几种尽量使用环氧树脂的良溶剂。

    2. Thin coating solvent quality control is good, epoxy floor paint run-off solution to a number of as far as possible use of epoxy resin good solvent.

    3、有些差的中涂含有大量不挥发增塑剂是造成表面跑油的主要原因。

    3, some bad medium coating contains a large amount of non-volatile plasticizer is the main reason for surface oil running.
